To all whzmz it may concern.-

Be it known that I, STUART ARCHER WEISS,

.a citizen of the United States, residing at Richa perspective view of my invention when set up for use. Fig. 2 is a vertical section of Fig. 1, cut on the line X X. Fig. 3 is a longitudinal section of my invention when the same is folded. Fig. 4c is an inside view of one of the arm-rests, part of the tray, and the means of holding the said tray to the arm. Fig. 5 is a sectional view of Fig. 4: on the line Y Y, the tray beingleft off. Fig. 6 is a perspective view of the arm-holders attached to one of the side beams of the web-frame. Fig. 7 is an inside view of one of the arm-rests, with means of attaching it to the arm-holders shown in Fig. 6. Fig. 8 is a perspective view ofpart of the beams, with a lock thereto attached. Fig. 9 is a perspective view of part of another beam, with the lock-bolt holder attached thereto. Fig. 10 is a perspective view showing one corner, part of a side beam, and part of an end beam of the webframe and part of the prop-frame, together with a catch secured to the end beam of the web-frame. two of the prop-frames at the point where they are locked and a view of the lock looking the frame.

My invention is described as follows: It consists of three light but substantial rectangular frames averaging in length about three feet and in width two feet. The two firstmentioned frames 1 and 2 are hinged together at their front ends by a substantial hinge 4, in such a way that these two frames when shut fit close together and completely inclose the third or prop frame. Said frame or prop- Fig. 11 is a sectional view 'of frame consists of three light frames (4, b, and 0 and are horizontally hinged together by butt or strap hinges 5, the top frame a being hinged to the rear end of the web-frame 2 by a sub-' stantial hinge, said frames (0, 5, and 0 being adapted to fold up on themselves, thereby giving greater or less pitch to the web-frame. Thus when the frame 0 is folded back the lower end of frame 6 rests against the rear end of the base-frame 1, and-when the frames cand I) are folded back the lower end of-frame a rests against the rear end of said frame 1. Thus in this position the web-frame is nearly on a horizontal line.

The prop-frame 3, consisting of the parts a, b, and c, is adapted to form a straight line and to be held in such position rigidly by locks 8,

consisting of a lock-case 8, carrying a hinged lock-bolt 8 said lock-bolt having a hook 8 and a lock-bolt holder 8, said lock-case being secured to a cross-beam of one of the frames a, and the lock-bolt holder 8i being secured to the adjoining frame 6. The frames 7) and 0 are held together by a similar device. The said prop-frame 3 is not quite so long-or so wide as the base-frame 1 and the web-frame 2, and said base and web frames are provided with recesses 9 and 10 in their inner edges to accommodate and envelop said prop-frame 3, so that when the two frames 1 and 2 come together said prop-frame is completely hidden and protected.

The rear cross-beam 11 of the base-frame 1 is provided with a lock cl, consisting of a case 12, carrying a lock-bolt 13, having on the free end of said bolt a hook 14. Said bolt is actuated by a spring 15. Secured to the crossframe 16 of the frame 0 is a lock-bolt holder 17 which constitutes a part of the lock d, and when the prop-frame 3v is in position as shown in Fig. 2 it is locked in said position by the lock-bolt 13 entering into the lock-bolt holder 17. Thislock-bolt 13 performs the additional function of locking the rear ends of frames 1 and 2 together by the hook 18, Fig; 10, entering the square perforation 19 in the lock-case 12, Fig. 8, the said bolt 13 catchingover the hook 18, Fig. 10.

Secured to the two side beams of the webframe 2 are slotted arm-holders 20. These arm-holders consist of metal straps bent so that their two parts are at right angles one with the other, one part, 21, being secured against the edge of the beam and the other part, 22, against the face of the beam. The parts 21 are each provided witha bayonetslot, While the parts 22 are provided with bedrail slots.

Adapted to fit and extend horizontally from the front face of the web-frame 2 are armrests 23. These arm-rests are each secured to a right-angle piece 24, provided with lockpins 25, adapted to enter into, slide down, and hold in said bayonet-slots and bed-rail slots. These arm-rests 23 are attachable and detachable, either, with two motions. Detachably secured to these arm-rests is a tray 26. This tray is secured to the upper edges of a couple of beams 27. These beams are each provided in their outer faces with a recess 28, and to theouter face of each beam is secured a spring-catch 29, provided each with a U- shaped recess bend 30, which may be forced back into the recesses 28. A springlock holder 31 is secured one to the outer face of each of said arm-rests provided each with a catch-bar 32. To fix the tray in place, we take hold of it and thrust the beams 27 into the spring-lock holders 31 until the U-bend passes the catch-bar 32, and to remove the tray we put the two index-fingers on the spring ends of the springs 29, press them down to the beams 27 and draw them out, and the tray is removed. Thus it is attached by one motion and detached by one motion.

The web-frame 2 is covered by a webbing 2 or other suitable material.

Though this invention is primarily intended for hospitals and sick-rooms, it may be used for army purposes. By stretching out the three frames 1, 2, and 3, laying them on the ground, and spreading over them an oil-cloth of any kind the soldier, sick or well, may be kept from coming in contact with the cold ground. By stretching out the three frames it may be used as a stretcher, because said parts are so hinged that when stretched out they become rigid on a straight line.

This invention may also be used as a seat by simply turning the tray over on the arms, (see Fig. 1,) and it may also be used as a table by setting the frames 1 and 3 in a vertical position and the web-frame 2 in a horizontal position and bracing the same by any suitable means.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A back and head rest, consisting of a base-frame 1, provided with an internal recess 9; a web-frame 2, hinged to said base-frame at its front end, and provided with an internal recess 10; a web covering 2, stretched over the upper face of said web-frame; a propframe 3, consisting of three small frames, (1, b and 0, hinged and locked together; the upper frame (1/, hinged to the rear end of said web-frame, and the lower end of flHlTlC (1, adapted to rest on the rear end of said frame 1, substantially as shown and described, and for the purposes set forth.

2. The combination of a rectangular baseframe 1, provided with internal recesses .l; a rectangular web-frame 2, hinged to said frame 1, at its front end, and provided with an internal recess 10; a web covering 2, stretched over the upper face of said web-frame; a propframe 3, consisting of three small frames, 1/, Z), 0, hinged and locked together; arm-rests 23, detachably secured to said web-frame, and a tray detachably secured to said arm-rests, substantially as shown and described, and for the purposes set forth.

3. In a back and head rest, slotted rightangle arm-holders 20, provided with a bayonet-slot in one wing and a bed-rail slot in the other wing, secured to the side beams of the web-frame 2; arms 23, extending from a rightangle piece 2%, and lock-pins 25, secured in said right-angle piece, and adapted to catch in the slots of the lock-holders 20, substantially as shown and described and for the purposes set forth.

a. In combination with a back and head rest, arm-rests 23; spring-loek holders 31, secured to the outer faces of said arm-rests, eaeh provided with a catch-bar 32; a tray 26, secured to two beams 27, each beam provided with a recess 28, in their outer faces, and springcatches 29, each provided with a U-shaped bend 30, adapted to rest in the recesses 23, substantially as shown and described and for the purposes set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
